The present invention provides a vapor injection heat pump system which has excellent heating efficiency even in an extremely low temperature state with a low outside air temperature. The vapor injection heat pump system comprises: a compressor compressing a refrigerant to discharge the refrigerant; a condenser condensing the compressed refrigerant; a first expansion means allowing the condensed refrigerant to pass therethrough or expanding the condensed refrigerant to transfer the refrigerant to the following outdoor heat exchanger or expanding the condensed refrigerant to transfer the refrigerant to the following gas-liquid separator in accordance with an air-conditioning mode; the gas-liquid separator separating the refrigerant expanded by the first expansion valve into gas and liquid, discharging the gaseous refrigerant to the compressor, and discharging the liquid refrigerant to the following outdoor heat exchanger or evaporator; the outdoor heat exchanger condensing or evaporating the refrigerant passing through the first expansion means or the refrigerant transferred by the gas-liquid separator; a second expansion means allowing the refrigerant transferred by the outdoor heat exchanger to pass therethrough or expanding the refrigerant to transfer the refrigerant to the gas-liquid separator, or transferring the refrigerant to the following accumulator in accordance with an air-conditioning mode; the evaporator using the refrigerant passing through the gas-liquid separator to cool indoor space; and the accumulator separating the refrigerant moving in the evaporator into gas and liquid to transfer the gas to the compressor.
